Specification of Letters Patent.

Application fil ed November 26, 1917. Serial No. 2033M.

Z '0 all whom it may concern.

Be it knownthat I, LOUIS Snrosm, a subject of the King of Hungary, having declared my intention to become a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in Ship-Protectors, of which the following is a specification.

This invention relates'to certain new and useful improvements in ship protectors.

The primary object of the invention is the provision of a protecting means for ships adapted for resilient mounting outwardly of the hull for slight movement under the influence of the wave, the device being adjustable fo protecting larger or smaller areas as required.

A further object of the device is the provision of armor plates adjustable in size adapted for preventin a torpedo or other missile from striking t e hull of a ship at or beneath the water level, suitable positioning means being arranged for cushioning the impact of the blow when a missile strikes one of the plates.

A still further object of the invention is the provision of a combined resilient and buoyant mounting means for a protector against torpedo attacks, the protector being when struck by a missile.

In the drawing forming a part of this application and in which like designating characters refer to corresponding parts throughout the several views.

Figure l is a side elevation of a ship provided with the protecting device.

Fig. 2 is a vertical transverse sectional view thereof.

Fig. 3 is an enlarged top plan view of a side portion of the same.

Fig. 4 is an enlarged detail view in longitudinal section of a portion of one of the floating support members and Fig. 5 is a transverse vertical sectional view through one of the protecting plate members. 7

The invention being designed for the protection of a ship from oncoming missiles approaching adjacent the water line of the hull, the device is herein illustrated in connection with a ship 10 having a hull 11, deck 12, cabin 13 and wireless outfit 14, while the invention broadly consists of telescoping armor plates 15 resiliently mounted in pluralityatopposite sides of the hull 11. The plates 15 consist of upper rectangular hollow sections 16 within which the solid lower plate sections 17 are slidably arranged in telescoping relations, while screws 18 journaled as at 19 in the top of the section 16 are threaded within sockets 20 of the lower section'17. A squared upwardly projecting head'21 is provided for the screws 18' and it will be understood that by turnin the screws by means of the heads 21 thereo the sections 17 may be'retracted within or projected from the sections 16, thereby al tering the area of the exterior surface of the plate 15.

Each of the plates 15 is mounted upon the adjacent side of the hull 11 by a plurality of combined resilient and buoyant connect- -ors 22, whereby the plate 15 will be maintained in floating arrangement at a normal distance from the side of the hull 11 for receiving and cushioning any blow from a torpedo or other missile aimed at the hull 11 adjacent the water line thereof.

The connectors 22 consist of hollow floats 23 pivoted to lugs 24 secured to the hull 11 while a longitudinally slotted link 25 is slidably arranged through a central bore 26 in the float 23 with the outer end of each link pivoted to a lug 27 upon the inner face of the adjacent plate section 16. The slot of link 25 receives a pin 28 in the outer end of a guide tube 29 which is provided with the bore 26 for receiving the link, thereby preventing the removal of the link from the float and maintaining the float and link in longitudinal alinement.

A helical spring 30 encircles the float 23 and its link 25 and being tensioned between one of the plate sections 16 and the adjacent side of the hull 11, the connector 22 is normally maintained substantially horizontal, with the armor plate 16 carried thereby in vertical arrangement outwardly of the hull. The floats 28 are arranged at or slightly beneath the surface of the water and it will be evident that in the event of a torpedo striking one of the plates 15, the said plate may move inwardly toward the hull 11 under the impact of the blow, with the blow cushioned by the spring 30 and the links 25 moving inwardly of the floats 23. A torpedo usually travels beneath the surface of the water so that the lower sections 17 of ornicn.
